5A Lithium Charger CV CC Buck Step Down Power Supply Module LED Driver


Product Description

Size: CC CV Voltage Regulator

Parameter: 

Frequency: 180KHz 

Weight: about 25g 

Input voltage: 4-38V 

Output power: 75W(Max) 

Transfer efficiency: 96%(Max) 

Output current: adjustabel;5A(Max) 

Input reverse connection protection: NO 

Working temperature: -40 to +85 Celsius 

Output voltage: 1.25-36V constantly adjustable 

Short-circuit protection: YES(limited current of 8A) 

Over-temperature protection: YES(item will stop output atomatically) 


Note: 

please strengthen cooling when buck converter module is used in more than 3A,35W 


Product functions: 

1.Work as high-power LED constant current driver module 

2.Work as buck converter module with over-current protection 

3.Charger of batteries(eg. nickel-cadimium or nickel-metal hydride battery, lithium batteries);can be used in solar panel/wind turbines/etc 


How to set current limits: 

1. Adjust constant-voltage potentiometer to make output voltage reach the voltage value which you want. 

2. Use 10A multimeter to measure short-circuit output current (directly connect two meters to output interface), at the same time, adjust constant-voltage potentiometer to make output current reach preset over-current protection value. (If the current value multimeter displays is 4A, the maxmum current of the module only can be up to 4A; when the current reach 4A, constant-voltage constant-current red indicator light is on, or the light is off) 


LED indicator light: 

1. Red light is on in constant current status and off in constant voltage status. 

2. Blue light is on when charging and off when full-charging 

3. Green light is on when full-charged. 


Package inclueds: 

1pcs Buck Converter
